Morphology

jack + in

The meaning 'to connect to a computer or network' is directly derivable from 'jack' (an electronic socket) plus the particle 'in' indicating insertion or connection. This follows the same transparent compositional pattern as 'plug in' and is therefore readily inferable by a B1 learner who knows both constituent meanings.

Etymology

The phrasal verb jack in comes from the image of plugging a cable into a jack, a small socket used to join one machine to another. So today jack in means 'to connect' or 'log on' to a computer or network.
